Subject: media: ov2740: Check hwcfg after allocating the ov2740 struct
Author: Hans de Goede <hdego...@redhat.com>
Date: Mon Dec 4 13:39:43 2023 +0100
Alloc ov2740_data and set up the drvdata pointer before calling
ov2740_check_hwcfg().
This is a preparation patch to allow ov2740_check_hwcfg()
to store some of the parsed data in the ov2740 struct.
